Waning Crescent Moon – Venus Conjunction

   Wednesday and Thursday mornings, May 1st and 2nd the 26 to 27-day old thin waning crescent Moon will pass by the inner planet Venus coming the closest on the 27th when the two will be separated by about 3-4o. A day later, Friday, the very thin waning crescent Moon will be near Mercury and the outer planet Uranus, but the Sun will be less than 45 minutes behind them – meaning the sky may be too bright to see the Moon or Mercury.
   Further to the west the outer planets Saturn and Jupiter are visible in the area around Sagittarius and Scorpius. Even a bit further west is the closest Dwarf Planet to the Earth, former asteroid Ceres.

Sun Enters Sagittarius

16dec-view-from-earth   Tuesday December 18th the Sun in its apparent eastward motion along the ecliptic, moves out of the constellation Scorpius the Scorpion and into the constellation of Sagittarius the Archer. This is the true or actual position of the Sun as opposed to the pseudoscience of astrology which usually has the astrological Sun one constellation ahead or east from the Astronomical Sun’s position.

   Read a little more about how astrology has the Sun incorrectly placed in a previous blog, and in another blog discussing the effects of precession.

Sun Not in Sagittarius

  According to the pseudoscience of astrology the Sun enters the constellation of Sagittarius the Archer on Thursday November 22nd. When in fact the actual position of the Sun is still within the boundaries of the constellation of Libra the Scales.

Saturn at Western Quadrature

saturn-west-quadrature   Thursay March 29th, the position of the planet Saturn with respect to the Earth and the Sun places this ringed planet at what is called western quadrature. Saturn is at a 90 degree angle from us as this graphic shows. Think third quarter Moon as that is a fair comparison of the relative positions. At this position Saturn leads the Sun across the sky from east to west as the Earth is rotating, meaning that Saturn rises before the Sun and also sets before the Sun.

Saturn currently is within the constellation of Sagittarius the Archer as this graphic shows. From the northern hemisphere, looking toward the southern horizon, you can find Saturn to the east, left, from the reddish star Antares. Between Saturn and Antares is Mars, about 2-3o from Saturn. To the right from Antares is the planet Jupiter.

   This is a short 5 minute video I made as part of a live musical performance called “Orbit”. This is a piece from the much longer tour of the solar system performance and video and shows Saturn and some of its moons as viewed from the Cassini spacecraft that month.

Sun Not in Capricornus, but it is the 2017 December Solstice

sag-cap-ani    According to the pseudoscience of astrology the Sun enters the constellation of Capricornus the Sea Goat on Thursday December 21st when in fact the actual position of the Sun is still within the boundaries of the constellation of Sagittarius the Archer.
In reality the Sun will have reached the celestial coordinates of 23.5o degrees south declination; 18 hours right ascension. With regard to the Earth’s surface this places the Sun over the Tropic of Capricorn, which is at 23.5o south latitude. We also know that it is the Earth’s tilt on its axis that is the cause for seasons on Earth rather than the distance between the Earth and the Sun. And of course we know that this signals the start of northern hemisphere winter and the southern hemisphere summer seasons.

The official time for the change of seasons is 1628 UT (1028 am CST).
earth-in-gemini

And for those ‘insanely curious’ like me, while the Sun is at 23.5o South declination and ‘in’ Sagittarius the Earth is opposite at 23.5o North declination and at the feet of the Gemini Twins.

The animated graphic below sets the stage, so to speak, to illustrate the Sun’s actual location with respect to the zodiac constellations in the background. This is as opposed to the location of the Sun according to the pseudoscience of Astrology. The scene is set for 12:15 CST, or mid-day when the Sun is at an azimuth of 180o, or south, and is mid-way between rising and setting. Starting with the Sun at mid-day the scene changes as first the daytime sky is turned off, followed by the horizon being turned off.
   This leaves a sky view like during a total solar eclipse except that the Sun is not blocked out by the new Moon. And like during that solar eclipse the zodiac constellations in the background become visible. Then the following are added starting first with Sagittarius, then Capricorn, and then the ecliptic and celestial equator are added to show the relationship between the two constellations and what makes them plus another 11 constellations the astronomical zodiac of 13 constellations. The animation ends with the addition of the constellation boundary lines and labels for the rest of the constellations in this setting.
It is the ecliptic, the apparent path of the Sun which, if it crosses the boundary of a constellation, makes that constellation one of the zodiac. And during December the Sun’s apparent path takes it across the constellation of Sagittarius rather than Capricorn.
